TrueMatch is fully integrated with the WITec Suite FIVE
software environment and is a perfect complement to
WITec’s data evaluation and post-processing components.

Generated reports can be stored for further use in
subsequent measurements, which turns meaningful results
into a valuable resource.

Easy Access, Quick Search, Positive Identification

Multi-spectral searches enable the user to identify several
spectra simultaneously, using databases to return hit rates
that describe the probability of a match for each individualspectrum.

TrueMatch is a powerful and innovative software component for accessing and developing
Raman spectral databases. With this technology, existing databases containing
representative Raman spectra of common materials or substrates can be searched and used
to identify the contents of a sample. It also allows users to create their own catalog ofspectra pertinent to their research.

Demix search uses databases to describe acquired spectrain terms of pure substances, which can then be physicallylocated in an image.

In addition to the proprietary WITec Raman databasecapability included with TrueMatch, compatible versions ofST Japan’s wide range of databases are available. Extensive
libraries of Raman spectra can be referenced while creating
your own, all from within WITec’s fully-integrated softwareand hardware environment.
